<2> An alarm A35920 in the temperature evaluation of the TM31 is signaled to the next (downstream) vector control via the
special temperature value -300 °C.
<3> As a result of the wire breakage monitoring the maximum temperature that can be measured is limited to approx.
188.6 °C.
<4> A value > 250 °C de-activates the alarm or fault.
<5> For KTY p4103 = 0 Output from TempTimer (0).
For PTC p4103 = 0 delay time = 0s.
